Design and Simulation of Distributed Optical Fiber Communication Protocol

摘要:

针对航天飞行控制系统特点,对比了光纤通道协议的三种拓扑结构的应用,对实际特定应用中功能与需求结合不紧密的方面进行研究,提出了一种适用于航天领域分布式控制的光纤通信协议；详细描述了协议的功能框架、拓扑结构和数据格式,基于FPGA搭建了通信协议的实现平台,着重描述了工作流程和状态机设计,最后对协议设计进行了多节点通信仿真；结果表明通信协议能够满足分布式控制需求；对于未来光纤总线在航天领域的应用具有推广意义。

Abstract:

For space flight control system features, the article compares the application of the three kinds of topology structure. And research the aspects of the function and the actual demand of specific application is not tightly combined. A type of optical fiber communication protocol of the field of aerospace distributed control is proposed. The functions of the framework agreement, the topology and data formats is described in details. In this paper a platform based on FPGA is built to realize the communication protocol, The workflow and the state machine design is focusing described. The simulation results of multipoint communication is given out at last. The article promotes the application of optical fiber in space.
